Leroy Hopson 8d76d3500c Update license text in file headers
With the exception of text_decoder.gd the code in these files follows
the original so closely that it doesn't qualify as an original work
and so there is nothing new to copyright.

Instead, the original license text is kept with a note mentioning the
port to GDScript.
